BLACS Build and Test Instructions:
----------------------------------

1. Navigate to the 'ScaLAPACK 1.8.0 for Windows' directory.

2. Run the set_environment.bat script with BLACS parameter:
   > set_environment.bat <ARCH> BLACS
where ARCH is x86 or x64
x86 architectre use MPICH2 and it will build 32 bits libraries.
x64 architecture use Microsoft MPI and it will build 64 bits libraries.

3. Navigate to the base BLACS directory from command prompt and build BLACS and
   test programs:

   > nmake mpi what=clean (optional)
   > nmake tester what=clean (optional)
   > nmake mpi
   > nmake tester

4. Navigate to BLACS\TESTING\EXE directory and execute the following commands to 
   test BLACS:

   > mpiexec -n 4 xCbtest_MPI-WIN64-0.exe
   > mpiexec -n 4 xFbtest_MPI-WIN64-0.exe 


SCALAPACK Build and Test Instructions:
--------------------------------------

1. Navigate to the 'ScaLAPACK 1.8.0 for Windows' directory.

2. Run the set_environment.bat script with the following parameters:
   > set_environment.bat <ARCH> ScaLAPACK 
     <BLAS library path> <LAPACK library path> [Precisions]
where ARCH is x86 or x64
x86 architectre use MPICH2 and it will build 32 bits libraries.
x64 architecture use Microsoft MPI and it will build 64 bits libraries.

3. Navigate to the base BLACS directory from command prompt and build BLACS:

   > nmake mpi what=clean (optional)
   > nmake mpi

   Please note that this step is optional and need to be performed if BLACS is 
   not built earlier.

4. Navigate to the scalapack-1.8.0 directory from command prompt and execute 
   the following command to build ScaLAPACK:

   > nmake all

5. Run the following script to test ScaLAPACK:
   
   > run_tests.bat


Notes:

    a. Enclose the provided BLAS and LAPACK library paths in double quotes if
       they contain spaces.

    b. By default, SCALAPACK gets built in "all" precision mode. To build it in
       any specific precision mode, for instance in single precision mode,
       provide "single" as a 4th parameter to set_environment.bat script.
       SCALAPACK can also be built in multiple precision mode by providing the
       combination like "single double".

    c. Please modify BLACS\BMAKES\Bmake.MPI-WIN64 file in case you need to
       configure some other options (For instance, FORTRAN 77 to C interface) 
       before running set_environment.bat script. You can directly modify
       BLACS\BMake.inc file if you have already setup the development
       environment.

    d. Please modify scalapack-1.8.0\INSTALL\SLmake.WIN64 file in case you
       need to configure some other options (For instance, FORTRAN 77 to 
       C interface) before running set_environment.bat script. You can 
       directly modify scalapack-1.8.0\SLmake.inc file if you have already 
       setup the development environment.

    e. If you have not installed Intel's C++ and Fortran compilers at 
       default location, modify set_environment.bat script to specify 
       approprite paths of iclvars.bat and IFortVars.bat.
